Background: Cardiac myxoma is the most common primary cardiac tumor. Even though it rarely causes a stroke, it is an important risk factor. Here, we compared our clinical experience in managing myxoma patients who developed stroke complications with those who did not present with this condition at the First Affiliated Hospital of Wenzhou Medical University.
Patients and Methods: The medical records were reviewed of 160 cardiac myxoma patients who were treated in our facility from January 2006 to December 2019. They were separated into either a stroke group or non-stroke group.
Results: Cardiac obstructive symptoms, embolic events and constitutional symptoms were observed in 92 (57.7%), 25 (15.6%) and 18 (11.2%) patients, respectively. Among 23 cardiac myxoma ischemic stroke patients, hypoesthesia (60.9%), hemiparesis (56.5%) and facial paresis (47.8%) were the three most common neurological symptoms. The middle cerebral artery (82.6%) was the most commonly affected vessel, whereas 73.9% of the ischemic patients had multiple stroke lesions. Binary logistic regression analysis showed that coronary heart disease and tumor sizes were independently associated in the stroke group (p < 0.05). The 10 years cumulative survival rate was 87.9% for all patients after surgical intervention. There was no significant difference in the 10 years cumulative survival rate between the two groups (80.0% vs 88.9%, p =0.274 > 0.05).
Conclusion: The three most common neurological symptoms (hypoesthesia, hemiparesis and facial paresis), the middle cerebral artery and multiple lesions involvements were the definitive markers of patients afflicted with cardiac myxoma stroke. Small tumor sizes were independently associated with these patients. Surgical resection is a relatively safe procedure for treating both the stroke and non-stroke patients.
